From 7a8231504928a4ad7a2229d0f8a27d9734159647 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ebtables: Fix corner-case noflush restore bug
JIRA: https://issues.redhat.com/browse/RHEL-14147
Upstream Status: iptables commit c1083acea70787eea3f7929fd04718434bb05ba8
commit c1083acea70787eea3f7929fd04718434bb05ba8

ebtables: Fix corner-case noflush restore bug
Report came from firwalld, but this is actually rather hard to trigger.
Since a regular chain line prevents it, typical dump/restore use-cases
are unaffected.
